Inappropriate implementation in Chrome for iOS in Google Chrome on iOS prior to 151.0.7922.72 allowed a remote attacker who convinced a user to engage in specific UI gestures to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data leakage in Google Chrome for iOS (versions prior to 151.0.7922.72) allows remote attackers to read cross-origin data by delivering a crafted HTML page that socially engineers the victim into performing specific UI gestures. The root cause is an inappropriate implementation classified under CWE-346 (Origin Validation Error), meaning Chrome's iOS-specific code fails to correctly enforce same-origin policy boundaries under particular interaction sequences. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome on iOS at a version strictly below 151.0.7922.72 - this flaw is specific to Chrome's iOS implementation and does not affect other platforms. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 3.1 with vector AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N accurately reflects a constrained real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a plausible domain and serves a crafted HTML page designed to visually prompt the victim - for example, framing a game mechanic or CAPTCHA interaction - that elicits the specific UI gestures required to trigger the origin validation bypass. When the iOS Chrome user on a version below 151.0.7922.72 visits the page and performs the prompted gestures, the page silently reads data from a cross-origin context (such as a logged-in session page) and exfiltrates it to the attacker's server. … |
| Remediation | The primary fix is upgrading Google Chrome on iOS to version 151.0.7922.72 or later, available through the Apple App Store. … Detailed patch versions, workarounds, and compensating controls in full report. |
